BackgroundThis systematic review and meta-analysis of Randomized Controlled Trials (RCTs) were conducted to determine the effects of coenzyme Q10 (CoQ10) supplementation on metabolic profiles of patients diagnosed with Chronic Kidney Disease (CKD).MethodsTwo independent reviewers systematically searched online databases including PubMed, Cochrane Library, and Web of Science databases, Scopus, EMBASE until July 2018 to identify eligible clinical trials. The heterogeneity across included trials was assessed using Cochran's Q test and I-square (I2) statistic. Cochrane Collaboration risk of bias tool was applied to evaluate the quality of selected RCTs. Standardized mean difference (SMD) and 95% Confidence Interval (CI) between two groups of intervention were used to determine pooled effect sizes.ResultsOut of 721 potential papers, 7 RCTs were appropriate to be included in our meta-analysis. The pooled results revealed that CoQ10 supplementation significantly reduced total-cholesterol (SMD=-0.58; CI, -0.94, - 0.21; P=0.002; I2: 54.9), LDL-cholesterol (SMD=-0.47; 95% CI, -0.78, -0.17; P=0.003; I2:00.0), malondialdehyde (MDA) (SMD=-3.0; 95% CI, -5.10, -0.90; P=0.005; I2: 95.4) and creatinine levels (SMD=-1.65; 95% CI, - 2.75, -0.54; P=0.003; I2: 95.0) in patients diagnosed with CKD. Triglycerides, HDL-cholesterol, fasting glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), and C-reactive protein (CRP) concentrations did not affect following CoQ10 supplementation.ConclusionOverall, the current meta-analysis demonstrated that CoQ10 supplementation significantly improved metabolic profile in patients with CKD by reducing total cholesterol, LDL-cholesterol, MDA and creatinine levels, yet it did not affect fasting glucose, insulin, HOMA-IR, and CRP concentrations.Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.
